Place a sheet of parchment paper on a baking sheet and mist with oil. Place steelhead skin-side-down on parchment and brush liberally with pesto. Sprinkle with nuts or crumbs and place in oven, roasting 12-15 minutes  until almost done inside, and browned on top.  Chef Michaelangelo (mick) Rosacci, www.TonysMarket.com
